Things like this really make it hard, as an atheist, to receive the argument that my problem is with Christianity, and not with religion.
You're saying that my beliefs mean there's no meaning, and are incompatible with flourishing in the world. I understand you feel the need to defend your beliefs as valuable and important, but somehow it seems almost impossible for religious people to do so without denigrating atheism.
And yes, a lot of atheists are dismissive of religion too. But look, I'll show you: I personally don't find religion necessary to live an ethical and fulfilling life, but I understand that many people find it valuable and compelling, and that's ok as long as they let other people live their lives too. I think people can be intelligent, rational, and respectful of the beliefs of others, while still maintaining their own religious beliefs.
There, that wasn't so hard, was it?
